ISAC-Assisted Channel Knowledge Map Generation for Physical Layer Authentication
Luca Bonaventura, Edoardo Gardin, Alessia Barison +2
Integrated sensing and communication (ISAC) enables the acquisition of environmental information by leveraging wireless signals transmitted for communication purposes. In this pape…
Security Analysis of RIS-Assisted Physical-Layer Authentication Over Multipath Channels
Linda Senigagliesi, Anna V. Guglielmi, Marco Baldi +1
In physical layer authentication, verification of a user's identity is based on the characteristics of the transmission channel through which signals are delivered to the authentic…
Physical Layer Authentication With Channel Knowledge Maps in Indoor Environments
Luca Bonaventura, Francesco Ardizzon, Stefano Tomasin
Physical layer authentication (PLA) allows to authenticate the user by comparing measurements over time, assuming their time consistency or by modeling their evolution. However, th…
Challenge-Response Authentication for LEO Satellite Channels: Exploiting Orbit-Specific Uniqueness
Jinyoung Lee, Stefano Tomasin, Dong-Hyun Jung
The number of low Earth orbit (LEO) satellite constellations has grown rapidly in recent years, bringing a major change to global wireless communications. As LEO satellite links ta…
Physical Layer-Based Device Fingerprinting for Wireless Security: From Theory to Practice
Junqing Zhang, Francesco Ardizzon, Mattia Piana +2
The identification of the devices from which a message is received is part of security mechanisms to ensure authentication in wireless communications. Conventional authentication a…
Physical Layer Authentication With Colored RIS in Visible Light Communications
Besra Cetindere Vela, Serkan Vela, Stefano Tomasin
We study a visible light communication (VLC) system that employs a colored reconfigurable intelligent surface (CRIS) based on dichroic mirrors that reflect light at tunable frequen…
